Improve CachingWrapperFilter to optionally also cache acceptDocs, if identical to liveDocs
------------------------------------------------------------------------------------------

                 Key: LUCENE-3531
                 URL: https://issues.apache.org/jira/browse/LUCENE-3531
             Project: Lucene - Java
          Issue Type: Improvement
          Components: core/search
    Affects Versions: 4.0
            Reporter: Uwe Schindler


Spinoff from LUCENE-1536: This issue removed the different cache modes completely and always
applies the acceptDocs using BitsFilteredDocIdSet.wrap(), the cache only contains raw DocIdSet
without any deletions/acceptDocs. For IndexReaders that are seldom reopened, this might not
be as performant as it could be. If the acceptDocs==IR.liveDocs, those DocIdSet could also
be cached with liveDocs applied.
